Chris Rock - Chris Rock Electrifies David Blaine During New York Stunt

The Grown Ups star was among the passers-by who stopped at New York's Pier 54 in Chelsea to gaze in awe at Blaine's electric spectacular, in which he wears a chain-mail body suit hooked up to two conductors for 72 hours, and jumped at the chance to control the Tesla coils sending currents coursing through his body.

Actors Woody Harrelson and Alicia Silverstone were also spotted in the crowd gathered around the site of the Electrified: One Million Volts Always On stunt, but both declined offers to take part.

Fans worldwide have also been encouraged to participate in the magician's endurance feat by helping to control the power of the surges at various sites around the world.

The three-day exercise, which is being streamed live online, is expected to end on Monday night (08Oct12).
